Description

本発明は、コイルに関するものである。   The present invention relates to a coil.

特許文献１，２等において、１本の平角線のエッジワイズ巻きによりコイルを形成する技術が開示されている。   Patent Documents 1 and 2 disclose a technique for forming a coil by edgewise winding of a single rectangular wire.

特許第３７３７４６１号公報Japanese Patent No. 3737461 特開２００７−３０５８０３号公報JP 2007-305803 A

ところで、銅板よりなる線材をエッジワイズ巻きするときにおいては、銅板よりなる線材に絶縁被膜を設けたものを曲げる、もしくは、銅板よりなる線材を曲げた後に絶縁被膜を被覆している。そのため、銅板よりなる線材を巻く際において、図７に示すように、曲げることにより銅板よりなる線材１００の内側が太ったり絶縁被膜が破れてしまったりすることがある。より詳しくは、銅板よりなる線材を薄くすると（Ｗ寸法を小さくすると）、断面積が小さくなるので断面積を稼ぐためにＬ寸法を大きくすることになる。この場合、曲げ加工の際の半径が大きくなり、外径側では引っ張り応力が加わる。その結果、外径側では絶縁被膜が破れる虞がある。また、内径側では圧縮応力が加わり、内径側において内径側端面には金型が位置して移動を規制していることにより銅板が厚さ方向に広がり（厚肉となり）内径側が太ることになる。   By the way, when an edgewise winding of a wire made of a copper plate is performed, the wire made of a copper plate is provided with an insulating coating, or the wire made of a copper plate is bent and then covered with the insulating coating. Therefore, when winding a wire made of a copper plate, the inner side of the wire 100 made of a copper plate may be thickened or the insulating coating may be broken by bending as shown in FIG. More specifically, when the wire made of a copper plate is thinned (when the W dimension is reduced), the cross-sectional area is reduced, so that the L dimension is increased to increase the cross-sectional area. In this case, the radius at the time of bending increases, and tensile stress is applied on the outer diameter side. As a result, the insulating coating may be broken on the outer diameter side. In addition, compressive stress is applied on the inner diameter side, and a mold is positioned on the inner diameter side end face on the inner diameter side to restrict movement, so that the copper plate spreads in the thickness direction (becomes thicker) and the inner diameter side becomes thicker. .

そのため、銅板よりなる線材１００を薄く幅広にすることは限度があった。また、銅板よりなる線材１００を重なるようにして巻くときに、図８（ａ）に示すように銅板よりなる線材１００の巻き太りにより隙間（空隙）Ｇａが発生してしまう。つまり、図８（ｂ）に示すように銅板よりなる線材１００を巻いて重ねた状態において巻き太りがまったく無ければ隙間Ｇａは発生しないが、図７を用いて説明したように巻き太りが発生すると軸方向の長さが同じターン数であっても不要に大きくなってしまっていた。   Therefore, there is a limit to making the wire 100 made of a copper plate thin and wide. Further, when the wire rods 100 made of copper are overlapped and wound, the gap (gap) Ga is generated due to the winding of the wire rods 100 made of copper as shown in FIG. In other words, as shown in FIG. 8B, the gap Ga does not occur if there is no winding thickness in the state where the wire 100 made of a copper plate is wound and overlapped, but when the winding thickness occurs as described with reference to FIG. Even if the axial length was the same number of turns, it was unnecessarily large.

本発明の目的は、軸方向の長さを小さくすることができるコイルを提供することにある。   The objective of this invention is providing the coil which can make axial length small.

請求項１に記載の発明では、軸方向に導線が螺旋状に巻回されたコイルであって、帯板状をなし、前記軸方向に螺旋状に巻回された絶縁性板材を備え、前記絶縁性板材の少なくとも一方の面に前記導線としての導電性部材を付着させてなることを要旨とする。   The invention according to claim 1 is a coil in which a conducting wire is spirally wound in the axial direction, has a strip shape, and includes an insulating plate spirally wound in the axial direction, The gist is that a conductive member as the conducting wire is attached to at least one surface of the insulating plate.

請求項１に記載の発明によれば、帯板状をなす絶縁性板材が軸方向に螺旋状に巻回され、この絶縁性板材の少なくとも一方の面に導線としての導電性部材を付着させているので、金属の板よりなる線材を曲げてコイルを構成する場合に比べて、軸方向の長さを同じターン数であっても小さくすることができる。   According to the first aspect of the present invention, the strip-shaped insulating plate is spirally wound in the axial direction, and a conductive member as a conductor is attached to at least one surface of the insulating plate. Therefore, the axial length can be reduced even when the number of turns is the same as compared to the case where the coil is formed by bending a wire made of a metal plate.

請求項２に記載のように、請求項１に記載のコイルにおいて、前記導電性部材は、めっき膜であると、製造が容易となる。
請求項３に記載のように、請求項１に記載のコイルにおいて、前記導電性部材は、金属箔であってもよい。 As described in claim 2, in the coil according to claim 1, when the conductive member is a plating film, the manufacture is facilitated.
As described in claim 3, in the coil according to claim 1, the conductive member may be a metal foil.

請求項４に記載のように、請求項１〜３のいずれか１項に記載のコイルにおいて、前記絶縁性板材における前記導電性部材の付着面に前記絶縁性板材の延設方向に沿って延びる突起が形成され、当該突起により、内径側の導線としての第１導電性部材および外径側の導線としての第２導電性部材が区画形成されていると、ターン数を大きくすることができる。   As described in claim 4, in the coil according to any one of claims 1 to 3, the coil extends along the extending direction of the insulating plate on the surface of the insulating plate to which the conductive member is attached. When the projection is formed and the projection forms the first conductive member as the inner diameter side conductor and the second conductive member as the outer diameter side conductor, the number of turns can be increased.

請求項５に記載のように、請求項１〜４のいずれか１項に記載のコイルにおいて、前記絶縁性板材および前記導線としての導電性部材における端部において締結用貫通孔を形成すると、形成した締結用貫通孔を用いて、端部において外部端子との接続を容易に行うことができる。   As described in claim 5, in the coil according to any one of claims 1 to 4, when a through hole for fastening is formed at an end portion of the insulating plate member and the conductive member as the conductive wire, the coil is formed. By using the fastening through hole, it is possible to easily connect the external terminal at the end.

本発明によれば、軸方向の長さを小さくすることができる。   According to the present invention, the axial length can be reduced.

以下、本発明を具体化した一実施形態を図面に従って説明する。
図１に示すように、コイル部品１０は、コイル２０とコア５０よりなり、コア付きコイルとなっている。コア５０としてＥ−Ｅ型コアを用いており、Ｅ−Ｅ型コアはＥ型コア５１とＥ型コア５２により構成されている。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
As shown in FIG. 1, the coil component 10 includes a coil 20 and a core 50 and is a coil with a core. An EE type core is used as the core 50, and the EE type core includes an E type core 51 and an E type core 52.

各Ｅ型コア５１，５２は、長方形の板状をなし水平方向に延設された本体部５５と、本体部５５の一方の面の中央部から突出する中央磁脚５６と、本体部５５の一方の面の端部から突設する両側磁脚５７，５８とからなる。中央磁脚５６および両側磁脚５７，５８はその断面が長方形をなしている。   Each of the E-shaped cores 51 and 52 has a rectangular plate-like main body portion 55 extending in the horizontal direction, a central magnetic leg 56 projecting from the central portion of one surface of the main body portion 55, and the main body portion 55. It consists of both-side magnetic legs 57 and 58 protruding from the end of one surface. The central magnetic leg 56 and the both side magnetic legs 57 and 58 have a rectangular cross section.

各Ｅ型コア５１，５２における中央磁脚５６の先端面同士が突き合わされる（両端面同士が対向配置される）。また、各Ｅ型コア５１，５２における両側磁脚５７，５８の先端面同士が突き合わされる（両端面同士が対向配置される）。Ｅ型コア５１，５２の中央磁脚５６における周囲にコイル２０が四角環状に巻回されて配置されている。   The front end surfaces of the central magnetic legs 56 in the E-type cores 51 and 52 are abutted with each other (both end surfaces are arranged to face each other). Moreover, the front end surfaces of the both-side magnetic legs 57 and 58 in the E-type cores 51 and 52 are brought into contact with each other (both end surfaces are arranged to face each other). The coil 20 is wound around the center magnetic leg 56 of the E-type cores 51 and 52 in a square ring shape.

図２に示すように、コイル２０は、軸方向に導線（４０）が螺旋状に巻回されたコイルである。導線（４０）は銅よりなる。コイル２０は絶縁性板材３０を備えており、絶縁性板材３０は、帯板状をなし、軸方向に螺旋状に巻回されている。   As shown in FIG. 2, the coil 20 is a coil in which a conducting wire (40) is spirally wound in the axial direction. The conducting wire (40) is made of copper. The coil 20 includes an insulating plate 30. The insulating plate 30 has a strip shape and is wound spirally in the axial direction.

図３（ａ），（ｂ），（ｃ）に示すように、絶縁性板材３０は、断面長方形の板を軸方向に延びる状態で螺旋状に巻回したものである。絶縁性板材３０は樹脂よりなり、押し出し成形により製作したものである。詳しくは、樹脂を板状に押し出しつつ軸方向に螺旋状に巻回したものである。この帯板状の絶縁性板材３０の厚さは０．１ｍｍ程度である。   As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, the insulating plate member 30 is a spirally wound plate having a rectangular cross section extending in the axial direction. The insulating plate 30 is made of resin and manufactured by extrusion molding. Specifically, the resin is spirally wound in the axial direction while extruding a plate. The thickness of the strip-like insulating plate member 30 is about 0.1 mm.

図３に示す絶縁性板材３０の両面（図面においては主表面３０ａおよびその裏面３０ｂの両方の面）に対し、図２に示すように、導線としての導電性部材４０が付着されている。導電性部材４０は銅のめっき膜であり、導電性部材４０の厚さは０．１ｍｍ程度である。巻回した絶縁性板材３０において重なり部分における一方の面（主表面３０ａ）に付着した導電性部材４０と他方の面（裏面３０ｂ）に付着した導電性部材４０とは接触して繋がっている。また、図３（ｄ）に網点で示したように絶縁性板材３０における両面（主表面３０ａ、裏面３０ｂ）に対し側面については導電性部材４０が付着されていない。   As shown in FIG. 2, a conductive member 40 as a conducting wire is attached to both surfaces of the insulating plate 30 shown in FIG. 3 (both surfaces of the main surface 30a and its back surface 30b in the drawing). The conductive member 40 is a copper plating film, and the thickness of the conductive member 40 is about 0.1 mm. In the wound insulating plate 30, the conductive member 40 attached to one surface (main surface 30 a) in the overlapping portion and the conductive member 40 attached to the other surface (back surface 30 b) are in contact with each other. Further, as indicated by the halftone dots in FIG. 3D, the conductive member 40 is not attached to the side surfaces of the insulating plate 30 on both sides (the main surface 30a and the back surface 30b).

なお、巻回した絶縁性板材３０において重なり部分における一方の面（主表面３０ａ）に付着した導電性部材４０と他方の面（裏面３０ｂ）に付着した導電性部材４０とは離間していてもよい。   In the wound insulating plate 30, the conductive member 40 attached to one surface (main surface 30a) in the overlapping portion and the conductive member 40 attached to the other surface (back surface 30b) may be separated from each other. Good.

図３（ａ），（ｂ），（ｃ）に示すように、１軸上に四角環状に巻回した絶縁性板材３０において一端が上方（外径側）に突出しており、接続端子部３１となっている。同様に、絶縁性板材３０において他端が上方（外径側）に突出しており、接続端子部３２となっている。   As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, one end protrudes upward (outer diameter side) in the insulating plate 30 wound in a square ring shape on one axis, and the connection terminal portion 31. It has become. Similarly, the other end of the insulating plate 30 projects upward (outer diameter side) to form a connection terminal portion 32.

図２に示すように、絶縁性板材３０の一方の接続端子部３１にも導線としての導電性部材４０が付着されている。同様に、絶縁性板材３０の他方の接続端子部３２にも導線としての導電性部材４０が付着されている。これにより、コイル２０において線材の一端が上方（外径側）に突出しており、接続端子（２５）として用いられる。同様に、コイルの他端が上方（外径側）に突出しており、接続端子（２６）として用いられる。   As shown in FIG. 2, a conductive member 40 as a conducting wire is also attached to one connection terminal portion 31 of the insulating plate 30. Similarly, a conductive member 40 as a conducting wire is attached to the other connection terminal portion 32 of the insulating plate 30. As a result, one end of the wire rod protrudes upward (outer diameter side) in the coil 20 and is used as the connection terminal (25). Similarly, the other end of the coil protrudes upward (outer diameter side) and is used as a connection terminal (26).

次に、コイル部品１０の製造方法について説明する。
まず、コイル２０の成形方法について述べる。
図３（ａ），（ｂ），（ｃ）に示すように、樹脂製の絶縁性板材３０を軸上に四角環状に巻回したものを成形する。このように、樹脂の絶縁物で先にコイルの形状を作る。そして、そこに導電性物質（導電性部材）を付着させて、図２に示す導電性のコイル２０を作る。付着方法には、めっきを用いる。めっきの場合、絶縁性板材３０をめっき液に漬けると良い。 Next, a method for manufacturing the coil component 10 will be described.
First, a method for forming the coil 20 will be described.
As shown in FIGS. 3A, 3B, and 3C, a resin-made insulating plate 30 is wound around a shaft in a square ring shape. In this way, the coil shape is first made of a resin insulator. Then, a conductive substance (conductive member) is attached thereto to form the conductive coil 20 shown in FIG. Plating is used as the adhesion method. In the case of plating, the insulating plate 30 may be immersed in a plating solution.

この際、図３（ｄ）において網点で示した領域、即ち、絶縁性板材３０の内側の側面および外側の側面はマスクされる。即ち、絶縁性板材３０の内側の側面および外側の側面をマスキングテープ等によりマスクして導電性物質（導電性部材）が付着しないようにする。あるいは、図３（ｄ）において網点で示した領域に着いた銅めっき膜を取り除くようにしてもよい。その後、必要に応じて絶縁被膜で被覆する。   At this time, the area indicated by the halftone dots in FIG. 3D, that is, the inner side surface and the outer side surface of the insulating plate 30 are masked. That is, the inner side surface and the outer side surface of the insulating plate member 30 are masked with a masking tape or the like so that the conductive substance (conductive member) does not adhere. Or you may make it remove the copper plating film which adhered to the area | region shown with the halftone dot in FIG.3 (d). Then, it coat | covers with an insulating film as needed.

図７，８を用いて説明したように従来のコイルでは銅板よりなる線材を薄くするとともにＬ寸法を大きくすると絶縁被膜が破れる虞があったり、銅板の内径側が太ることにより銅板を薄くして幅広にすることは限度があったり、巻き太りにより軸方向の長さが不要に大きくなってしまっていた。   As described with reference to FIGS. 7 and 8, in the conventional coil, if the wire made of a copper plate is thinned and the L dimension is increased, the insulating coating may be broken, or the copper plate is thinned and widened by increasing the inner diameter side of the copper plate. There is a limit to this, and the length in the axial direction has become unnecessarily large due to thickening.

これに対し本実施形態では、軸方向に螺旋状に巻回された絶縁性板材３０に導線としての導電性部材４０を付着させることにより、導通部の薄型幅広化、曲げ太り軽減を図ることができる。また、製作コストを低減することができる（金属製線材の成形よりも樹脂製絶縁性部材の成形のほうが容易である）。さらに、コイルの形状についての自由度がアップする。   On the other hand, in this embodiment, by attaching the conductive member 40 as a conductive wire to the insulating plate 30 wound spirally in the axial direction, it is possible to reduce the thickness and width of the conductive portion and reduce the bending thickness. it can. In addition, the manufacturing cost can be reduced (molding of the resin insulating member is easier than molding of the metal wire). Furthermore, the freedom degree about the shape of a coil improves.

引き続き、このようして製造したコイル２０に対し、図１に示すように、コイル２０にＥ型コア５１，５２の中央磁脚５６を挿入してＥ型コア５１，５２における中央磁脚５６および両側磁脚５７，５８の先端面同士を接近して対向配置させる。その結果、図１に示すコイル部品１０が製造される。   Subsequently, as shown in FIG. 1, the center magnetic legs 56 of the E-type cores 51 and 52 are inserted into the coil 20 to the coil 20 thus manufactured, The front end surfaces of the magnetic legs 57 and 58 on both sides are arranged close to each other and face each other. As a result, the coil component 10 shown in FIG. 1 is manufactured.

上記実施形態によれば、以下のような効果を得ることができる。
（１）軸方向に導線が螺旋状に巻回されたコイル２０の構成として、帯板状をなし、軸方向に螺旋状に巻回された絶縁性板材３０を備え、絶縁性板材３０の両面（主表面３０ａおよび裏面３０ｂの両面）に導線としての導電性部材４０を付着させた。よって、金属の板よりなる線材を曲げてコイルを構成する場合に比べて、軸方向の長さを同じターン数であっても小さくすることができる。 According to the above embodiment, the following effects can be obtained.
(1) As a configuration of the coil 20 in which the conductive wire is spirally wound in the axial direction, the coil 20 has a strip shape, and includes an insulating plate 30 spirally wound in the axial direction. Conductive member 40 as a conducting wire was attached to (both surfaces of main surface 30a and back surface 30b). Therefore, the axial length can be reduced even when the number of turns is the same as in the case where the coil is formed by bending a wire made of a metal plate.

（２）導電性部材４０は、めっき膜であるので、製造が容易となる。
なお、本実施形態ではコイルは線材を軸方向に螺旋状に巻回したスパイラル形状であったが、線材を同一平面に渦巻き状に形成した、いわゆる平面コイルであると、コイルが径方向に巻回される。この平面コイルにおいては、ターン数（巻数）が多いと径方向に大型化するのでターン数（巻数）が限られるとともにターン数（巻数）を多くするためには積層せざるをえない。しかし、積層すると製造が複雑になる。また、コア形状も限られることになる。これに対し本実施形態では、大型化を招くことなくターン数（巻数）を多くすることができるとともに容易に製造することができ、さらに、コアの形状の自由度も高くできる。 (2) Since the conductive member 40 is a plating film, the manufacture becomes easy.
In this embodiment, the coil has a spiral shape in which a wire is spirally wound in the axial direction. However, in the case of a so-called planar coil in which the wire is spirally formed on the same plane, the coil is wound in the radial direction. Turned. In this planar coil, when the number of turns (the number of turns) is large, the size is increased in the radial direction. Therefore, the number of turns (the number of turns) is limited and the number of turns (the number of turns) must be increased. However, stacking complicates manufacturing. Also, the core shape is limited. On the other hand, in the present embodiment, the number of turns (number of turns) can be increased without increasing the size, and it can be easily manufactured, and the degree of freedom of the shape of the core can be increased.

実施形態は前記に限定されるものではなく、例えば、次のように具体化してもよい。
・図４に示すように、絶縁性板材３０における導電性部材の付着面に絶縁性板材３０の延設方向に沿って延びる突起３５を形成し、図５に示すように当該突起３５により、内径側の導線としての第１導電性部材４５および外径側の導線としての第２導電性部材４６を区画形成してもよい。そして、外部において、内径側の導線としての第１導電性部材４５の一端と外径側の導線としての第２導電性部材４６の一端とを電気的に接続する。これにより、ターン数（巻数）を大きくすることができる。具体的にはターン数を２倍にすることができる。 The embodiment is not limited to the above, and may be embodied as follows, for example.
As shown in FIG. 4, a projection 35 extending along the extending direction of the insulating plate 30 is formed on the surface of the insulating plate 30 to which the conductive member is attached. The first conductive member 45 as a side conductor and the second conductive member 46 as an outer diameter side conductor may be partitioned. Then, at the outside, one end of the first conductive member 45 as the inner diameter side conductor is electrically connected to one end of the second conductive member 46 as the outer diameter side conductor. Thereby, the number of turns (the number of turns) can be increased. Specifically, the number of turns can be doubled.

このようにして、絶縁性板材３０に突起３５を設けることで容易にターン数を増やすことができる。
・図６に示すように、絶縁性板材３０は先端部が引出し部となるが、当該部位に貫通孔３７を形成し、この部位の表面に導電性部材４０を付着させる。即ち、絶縁性板材および導線としての導電性部材における端部２５，２６において締結用貫通孔９０を形成してもよい。締結用貫通孔９０は、ねじが通る貫通孔である。この場合、形成した締結用貫通孔９０を用いて、端部において外部端子との接続を容易に行うことができる。つまり、引出部にて絶縁性板材３０に貫通孔３７を設けることで締結用貫通孔９０を設けて締結部位を確保することが可能となる。 Thus, the number of turns can be easily increased by providing the projection 35 on the insulating plate 30.
As shown in FIG. 6, the tip of the insulating plate 30 is a lead-out portion, but a through hole 37 is formed in the portion, and the conductive member 40 is attached to the surface of the portion. That is, the fastening through hole 90 may be formed at the end portions 25 and 26 of the insulating member and the conductive member as the conducting wire. The fastening through hole 90 is a through hole through which a screw passes. In this case, it is possible to easily connect the external terminal at the end using the formed through hole 90 for fastening. That is, by providing the through hole 37 in the insulating plate 30 at the lead-out portion, it is possible to provide the fastening through hole 90 and secure the fastening portion.
